Description

  The present invention relates to a cleaning apparatus for cleaning, for example, root vegetables such as radishes and carrots, and machine products having a cylindrical shape or a polygonal cross section.

  A conventional cleaning apparatus includes a plurality of cleaning rolls arranged in parallel at predetermined intervals, and a polishing body disposed above the plurality of cleaning rolls, and the plurality of cleaning rolls and the polishing body In the meantime, crops such as radishes were arranged along the axis of the cleaning roll, and the plurality of cleaning rolls were rotated to clean the surface of the crop while conveying the crop (Japanese Patent Laid-Open No. 2003-2003). No. 230372: see Patent Document 1).

  However, in the conventional cleaning device, since the axis of the cleaning roll coincides with the longitudinal direction of the crop, it is necessary to make the length of the cleaning roll longer than the length of the crop. The rolls were large and expensive. In addition, since the crops were being conveyed while being rotated only by the rotation of the plurality of cleaning rolls, the crops could be idle, and the entire circumference (whole) of the crops could not be cleaned cleanly. . And many washing | cleaning rolls were required in order to wash | clean the circumference | surroundings of the said crops cleanly.

Thus, the conventional cleaning apparatus is large in size, inconvenient to move, and requires a wider work space. Moreover, dirt (such as mud) on crops could not be removed cleanly.

On the other hand, when the maximum radius portion of the first non-circular gear 71 and the minimum radius portion of the second non-circular gear 72 are engaged with each other, the second non-circular gear 72 with respect to the first non-circular gear 71 is engaged. The reduction ratio is minimized, and the traveling speed of the second conveyor 12 is the largest with respect to the traveling speed of the first conveyor 11.

  In this manner, the speed of the second conveyor 12 with respect to the speed of the first conveyor 11 can be gradually decreased. That is, the conveyor speed control means 14 is configured by the first non-circular gear 71, the second non-circular gear 72, and the like.

  Next, with reference to FIG. 1 to FIG.

  First, the engine 30 is driven to cause the first conveyor 11 and the second conveyor 12 to run, and the rotary brush 2 is swung back and forth while rotating.

  Then, the worker T places the other end side (root side) of the object to be cleaned S on the hopper 4 so that one end side (leaf side) of the object to be cleaned S is placed on the first conveyor 11. throw into.

  Then, the object to be cleaned S is transported by sandwiching one end side of the object to be cleaned S from above and below by the first conveyor 11 and the second conveyor 12. At this time, the traveling speeds of the first conveyor 11 and the second conveyor 12 are different by the conveyor speed control means 14 (the first non-circular gear 71 and the second non-circular gear 72). The to-be-cleaned object S rotates. The upper portion of the chain 11c of the first conveyor 11 is lowered by the spring portion 11d of the first conveyor 11 in accordance with the size of the object to be cleaned S.

  And the said to-be-cleaned object S conveyed while rotating passes between the said upper and lower rotary brushes 2 and 2, bathing in the washing | cleaning liquid discharged from the said 1st washing | cleaning pipe | tube 6a. At this time, since the rotary brush 2 is swung in the front-rear direction by the rotary brush reciprocating means 24, the rotary brush 2 comes into contact with the entire length of the article S to be cleaned.

  Thereafter, the article S to be cleaned is carried out from the first conveyor 11 and the second conveyor 12 to the chute 5. At this time, since the object to be cleaned S is exposed to the cleaning liquid discharged from the second cleaning pipe 6b, it is cleaned cleanly without being left behind.

  Thus, in this cleaning apparatus, the object to be cleaned S can be cleaned while being rotated, and the entire outer peripheral surface of the object to be cleaned S can be reliably cleaned. Further, since the rotary brush 2 is reciprocated while rotating, the entire length of the object S to be cleaned can be reliably cleaned. Further, since the speed of the second conveyor 12 with respect to the speed of the first conveyor 11 is gradually decreased and gradually increased, the object to be cleaned S is rotated smoothly and efficiently in the forward and reverse directions, and the rotating brush. 2 can be brought into contact with the workpiece S from various angles.

  Further, since the rotating brush 2 is disposed substantially along the conveying direction of the object to be cleaned S, the rotating brush 2 is disposed substantially perpendicular to the longitudinal direction (axial direction) of the object to be cleaned S. In addition, since the object to be cleaned S is cleaned while being rotated, the dimension (full length) of the rotating brush 2 in the longitudinal direction can be shortened. Further, since the rotary brush 2 is reciprocated while being rotated, the outer diameter of the rotary brush 2 can be reduced and the number of the rotary brushes 2 can be reduced, thereby reducing the size and cost of the rotary brush 2. Can be planned.

  Further, since the object to be cleaned S is cleaned with the rotating brush 2 arranged substantially along the conveying direction of the object to be cleaned S, the rotating brush 2 is rotated around the object to be cleaned S. Along the direction and the longitudinal direction, cleaning can be performed by bringing them into contact with each other, thereby increasing the cleaning effect.

  Therefore, in the cleaning apparatus having the above-described configuration, it is possible to reduce the size and weight, and to clean the object to be cleaned S cleanly.

  For example, radish with leaves harvested in the field needs to be washed before shipping. There are also dried radishes that are exposed to the sun and dried to produce a product, which must also be washed before drying. At this time, the use of the above-described cleaning device is small and lightweight, so that it is convenient for movement between fields, and installation and work space can be reduced.

  As described above, in the cleaning apparatus, the object to be cleaned S can be continuously and automatically cleaned with high efficiency and high accuracy by simply sandwiching the object to be cleaned S between the pair of conveyors 11 and 12.

  In addition, this invention is not limited to the above-mentioned embodiment. For example, the rotating brush may not be reciprocated. Moreover, you may make it drive | work the running surface which the said pair of conveyor opposes to a reverse direction, or to stop the running surface of one conveyor. Further, the rotary brush may be translated in the front-rear direction so as to approach or separate from the conveying means. In addition to the elliptical gear, the non-circular gear may be an oval gear or the like, or a large and small gear may be used instead of the non-circular gear. Further, the speed of the pair of conveyors may be constant without gradually decreasing and gradually increasing. In addition, an electric motor or the like may be used as a driving source of the cleaning device instead of the engine 30, which is suitable for indoor work or the like. Further, as a drive means such as the conveyor drive means 13 and the rotary brush drive means 23, a hydraulic pump is driven by the engine 30 (or an electric motor or the like) instead of the belt transmission part and the chain transmission part, A hydraulic device such as a motor may be used. The cleaning liquid is ordinary water, an organic solvent, a chemical cleaning liquid, or the like.
